The firing member includes a hub 2,6 and radially Xtending actuatingblades 27, 28 and 29. As shown these blades are twist ed into an arcuateshape in order to efiectively bring about the operation of the hammersas will be hereinafter more fully described. V p

Arranged in rear of and below, the plane of the shaft 14 is a shaft 30on which is rockably mounted the trip arms 31 and 32. The trip 31engages one hammer 13, while the trip arm 32 engages the other hammer l3and these trip arms normally prevent the swinging movement .of the hammers into engagement with the firing pins 12. The rear terminals of thetrip arms 31 and 32 are provided with inwardlydirected lugs 33 which liein the path of the blades 27, 28 and 29 formed on the firing member 20.Disposed in rear of the shaft 17 is a transversely extending shaft 34 onwhich is rockably mounted the hammer operating members35 and 36. Thesemembers 35 and 31 and '32. bifurcated to provide a pair of divergingactuatedarms '37 and 38. The arm 37 extends forwardly beyond the lowerarm 38 and is connected to the arm 16 formed on the hammer by means of alink 39.

The lower arm 38 isprovided with an arcuate depending foot 410 whichnormally rests upon the upper surface of the trip members 31 and 32adjacent to the trip wheel 20.

In order to normally hold the trip wheel 20 against accidental movementas the same has been actuatedby the trigger 22 an eX- pansion spring 41is'coiled about the shaft 17 'andthe upper end of this spring bearsagainst the frame of the gun, while the lower end thereof frictionallyrests upon the said wheel 20.

In use of the improved fire arms, the trigger 22 is pulled back in theusual manner, which will force the pawl 24 forwardly and rotate theratchet disk19. "The rotation of theratchet disk 19 will rotate theshaft 17 and the wheel 20. This will move the blade 27 into engagementwith the inner end of the trip arm 31 and raise the same and move theforward end of the trip arm below the hammer on the right-hand side andout of engagement with the teeth formed thereon. The raising of theinner end of the trip arm 31 will lift the operating member 35 and thusactuate the hammer through the medium of the link 39 and forcibly movethe same into engagement with its firing pin. The blade 28 on the wheel20 will now be disposed adjacent to the inner end of the trip arm 32 andwhen the trigger 22 is again pressed the shaft will be again rotated andthe trip arm 32 thus causing the operation .of the left-hammer 13 andcausing the'firing of the left-hand barrel.

The gun can now be broken for the ejection of the fired cartridges andpermitthe new cartridges or shells to be placed in position.

From the foregoing description, it can be seen that I have provided an'improved tripping device for double barrel shot guns and the like whichwill permit the operation of first one barrel and then the other by theuse of a single trigger.

Changes in details may be made without 'departingffrom the. spirit orthe scope of this invention.

-WhatI claim as new is In a firearm, a pair of barrels, a firing pin foreach barrel, a hammer for each firing pin, a pivoted trip arm foreach'hammer,an operating member for each hammer including a pair ofdiverging arms, means connecting one arm to each hammer, the other armengaging the trip arm, a rotary shaft arranged between the trip arms andoperating members, a ratchet disk keyed to the shaft, a trip Wheelincluding a plurality of radiating blades keyed to the shaft, means .fornormally holding the trip wheel in a predetermined position againstaccidental movement, a single trigger, means normally holding thetrigger in a predetermined position, and a pawl carried by the triggerfor engaging the. ratchet disk for bringing about'the rotation of theshaftrupon each time the trigger is pulled.

In testimony whereofI aflix my signature in presence of two witnesses.
